If you do not have lab resources to test your upgrade and you are forced to do your proof of concept in production, there are some things you can do to minimize your downtime.

 

 

1) If you have an HA pair, upgrade only one unit, failover to it, if all things are working after a few days, upgrade the other unit. Note that you probably won't want to synchronize your pair during this time, and if you are mirroring connections, you might want to disable that as well.

 

 

2) If you don't have an HA pair, upgrade only 1 of the boot slots to the new version, that way if it fails, you can switchboot back to your current setup within minutes.
